ARTIFICIAL TOOTH.

SPECIFICATION forming part of Letters Patent No. 249,724 dated November15, 1881,

Application filed Septemberll, IP81. (No modcl.)

To all whom it may concern:

Be it known that I, JAMES O. FLOWER, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have made a new and usefulImprovement in Artificial Teeth, of which the following is aspecification.

The object of my invention is to provide an artificial tooth that may bepivoted and fastened to the natural root in such a manner as to bepermanent, and at the same time make the joint between them whollyimpervious to the moisture of the mouth, whereby the ill eft'ectsarising from the accumulation ofofiensive matter is completely andeffectually avoided.

The nature of my invention will be readily understood from the followingdescription, taken in connection with the accompanying drawings, whereinFigure 1 represents a transverse vertical section of an artificial toothattached to a natural root in accordance with the plan of my invention;Fig. 2, a conjoint front elevation of the root and tooth; Fig. 3, a sideelevation of the same; Fig. 4, a very thin and small metallic cup.

The cup A may be made of various sizes, but usually from one-eighth tothree-sixteenths of an inch deep, and of a width a little greater thanthe maximum diameter of the exposed portion of an ordinary natural root.The edge of this cup should be very thin and flexible. As thusconstructed the cup is to be fitted to the base and inner side of theartificial tooth B by sol dering its apex to a plate, 0, firmly rivetedthereto, and a metallic pin, D, is at the same time to be soldered inthe center of the cup, its outer end extending above its rim half aninch or more, as the case may require. The tooth having been'soprepared, a hole corresponding with the'diameter of the pin is to bedrilled centrally into the natural root E in the direction of itslength, when its upper portion may be smoothed, filed off, or leftrough. When the pin I) is inserted in this hole the edge of the cup illoverlap the exposed portions of the root. The cup is then-to be filledwith some suitable cement, and the edge of the cup tightly compressedaround the upper end of the natural fang, whereby all moisture and othermatter is wholly and effectually excluded.

Having thus briefiy'described my invention, what I claim, and desire tosecure by Letters Patent, is-

As an improvemeuti'n artificial teeth, the thin flexible cone-shaped capsecured by its apex to the plate 0, that is riveted to the toothcrowu,and provided with a pin, D, secured as described.
